PN EU MATIC-TIRE REPAIRER.

SPECIFICATION forming part of Letters Patent No. 650,910, dated June 5,1900.

Application filed September 18, 1899. Serial No. 730,868. (No model.)

To all whom it may con/cern:

Be it known that I, GEORGE READING, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Pneumatic-Tire Repairer, ofwhich the following is a specification.

My invention relates to repair-kits for repairing tires, and has for itsobject. to provide an improved plug and means for inserting and securingit in the tire, so that the puncture or hole will not be materiallyincreased.

With this object in view my invention consists in the parts andcombination of parts, as will be fully described hereinafter,illustrated in the accompanying drawings, and recited in the claims, allforming a part of this specification. j

In the drawings, Figure 1 is a sectional view of a tire of any approvedconstruction, showing the manner of inserting the plug therein. Fig. 2is a vertical longitudinal section of the plug. Fig. 3 is a top planview of the same. Fig. 4 is a side elevation of the tool for inserting amodified form 0f plug. Fig. 5 is a vertical longitudinal section of thecement-applying receptacle. Fig. 6 is a side elevation of the tool forinserting the plug shown in Fig. 2. Fig. 7 is a side elevation of thecutter for making thesidey walls of the puncture smooth and even beforeinserting the plug, and Fig. 8 is a vertical 'longitudinal section of amodified form of plug.

Referring now to the drawings by referencenumerals, 8 represents thecutter for cutting the edges of the opening caused by some sharp objectwhich has punctured the tire and has a cutting edge 9 at its lower end.

l0 represents the cement-holding receptacle, comprising the hopper-likeportion l1, contracted at 12 to form a tube, which terminatesin aright-angular extension 13, pointed at its end and having a series ofopenings or perforations 14 at its upper edge through which the adhesivematerial may be forced.

15 represents the plug employed in connection with my repairkit andconsists of a concavo-con Vex bottom 16, provided with a concentricallyarranged upwardly projecting stem 17, on the end of which is secured aflexible cord of any desired length. Secured to or molded integral withthe top edges of the bottom portion 16 is a lIiat top or cover 18,having a tubular projection 19 extending from its center in line Withand of about the same diameter as the stern 17. This plug will be madeof thin rubber, in order that the top and bottom portions may be broughttogether, as will be hereinafter explained. The stem 17 4is' preferablymade longer than the distance from'the bottom to the top of the plug, s0that its top will normally be forced over to one side, as shown in Fig.2, out of the Way of the ipserting-tool. The tip of the stem ispreferably formed tapering or Wedge-shaped for the reception of theflexible cord and also to cause it to readily enter the tubularprojection 19.

The inserting-tool consists of an elongated piece of wire 20 of sufcientgage to insure rigidity, provided with an eye at one end and aright-angular roughened projection 21 upon the other.

The plug will be applied as follows: Cement being placed in thereceptacle provided for that purpose the contracted portion thereof isthen inserted in the opening in the tire. The right-angular extension isthen turned around inside the tire while the cement is being forcedthrough the perforations until a sufficient amount is distributed overthe inner surface of the tire. The cement-receptacle is then withdrawn,and after inserting the plug by the tool described the tool is withdrawnand the projections are pulled through the opening made in the tire.When the plug is used in the form shown in Fig. 2, a sufficient amountof cement will be inserted through the tubular projection to insure thebottom and top being cemented together.

In the modified form of my kit a plug similar to the one shown in Fig. 8will be employed, comprising the concavo-convex disks 25, having a stem26. In inserting this form of plug a tool such as is shown in Fig. etwill be used. This tool comprises a rigid mem# ber 27, reduced at oneend and at the other having an elongated recess 2S to hold cement and achannel 29, through which it is forced into the tire by means of theplunger 30. Intermediate the ends .of this member are provided ears 81,to which a pivoted member 32 is secured, and the lower'ends of the twomembers are normally held in contact by a spring 33. Each member isprovided with IOO a cut-out portion 34 for the exit of the cement, andtheir ends are concave to coliform to the stein of the plug.

In inserting the last-named plug the steni is grasped between the twolower concave ends of the pincers formed by pivoting these memberstogether and inserted in the usual manner until the channel 29 isadjacent to the inner wall of the tire, when the plunger is forced downand the cement is forced through. The pincers are then withdrawn, andthe plu g will adhere to the tire similar to those now in use.

In both processes the tires are inflated in the usual manner, which willhave a tendency to assist the plug to remain against the wall of thesame until the cement hardens.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

l. In a bicycle-tire repairer, the combina tion, with a hollow plughaving a convex bottom and a iiat top, the top being provided with acentrally-located tubular projection and the bottom being provided witha stem in alinement with the projection, and of a larger diameter thanthe bore of the same, the upper end of the stem being tapered, of aflexible cord secured to the tip of the stem and extending through theprojection, substantially as described.

2. In a bicycle-tire repair-er, the combination, with a hollowsubstantially-semispherical plug, the top of which is provided with acentrally-located tubular projection and the bottom is provided with astem upon the interior in alinelneut with the projection, of a cordsecured to the plug and extending through the tubular projection, and aninsertion-tool, the outer end of which is provided with a handle and theinner end is bent into a laterally-extending roughened projection forengaging with the inner surface of the fiat top to rotate the plug uponthe interior of the tire, substantially as described.
